Guerra, J., Gallego, M. T., Jiménez, J. A., Lüth, M. & Pedrocchi-Rius, C. 2021. The rare moss Cinclidotus vivesii Ederra, a case of interspecific hybridization. – Herzogia 34: 267–278.
Cinclidotus vivesii Ederra was described as a new species, although it has not subsequently been collected outside of the type locality. A study based on specimens morphologically close to this species, from the north of the Iberian Peninsula, and samples of the known European species of Cinclidotus, using the sequences of the plastid rps4 and ITS2 of rDNA regions, has shown that C. vivesii is an interspecific hybrid between C. aquaticus (male parent) and C. riparius (female parent). Cinclidotus ×vivesii nothosp. & stat. nov. is proposed for specimens from the only known population, previously described as a species.
